At the mums & children's group I go to, the children range between a few weeks (antenatal group is next door and you just swap rooms) and a few years old. Its generally a really lovely environment, albeit a bit groupy to begin with; DS is 4 months and I'm just about settled in!
Recently some new members have joined, and I haven't spoken to them much, as they tend to sit in the corner on their phones, and ignoring the rest of us if we try and strike up conversation
But anyway - one of these mums has a little boy who is about 16-18 months (I'm guessing here, as when I asked her before, she just looked at me blankly and went back to her phone). Today she gave him a piece of ham off her plate to eat and he dropped it. He then picked it up and went to eat it again, to which she shouted, "Don't act like a bloody tramp!"
I didn't say anything (not my place) but it really shocked me, and some of the other members in the room.
